New records, neotype designation and DNA sequences of three species of Chaetonotus (Gastrotricha: Chaetonotidae) from Brazil.

Gastrotrichs are aquatic microinvertebrates (less than 1 mm long) commonly found in freshwater and marine environments worldwide. The taxonomy of gastrotrichs is mainly based on external morphological characters, such as body shape and size of the different body regions, presence and distribution of adhesive tubules, or the microstructure of the external cuticle (e.g.

[Evaluation of the cost-effectiveness of an integral model of ambulatory treatment in patients with acute coronary syndrome: application of a probabilistic Markov modelAvaliação da relação custo-eficácia de um modelo integral de tratamento ambulatorial em pacientes com síndrome coronariana aguda: aplicação de um modelo probabilístico de Markov].

Objective: To evaluate the cost-effectiveness of an integral model of ambulatory treatment in patients who presented an acute coronary syndrome.

Methods: An economic evaluation was made from a quasi-experimental intervention study, which included 442 patients aged 30 to 70 years who presented an acute coronary syndrome. The intervention group (n = 165) received an integral model of ambulatory treatment based on managed care (disease management), while the control group (n = 277) received conventional cardiovascular rehabilitation.
